Description

[0001] The present invention relates to a support leg for swap bodies of trucks with a leg that can be fixed to a frame of a vehicle and a leg that is vertical in a support position, which has an upper tube and a telescopic lower support tube on which a pressure distribution plate is mounted immovably but rotatably about a rotation axis.

[0002] DE 10 2019 125 940 B4 discloses a support leg for swap bodies that can be pivotally mounted on the frame of a truck or trailer. To limit the surface pressure on the underside of the support leg, two pressure distribution plates are pivotally mounted on a lower support tube and can be folded up for the transport position and pivoted down for the support position. In the downwardly pivoted position, the pressure distribution plates can be secured via a locking element that is slidably mounted on the support tube. While this allows for weight load distribution, numerous components are required to distribute the pressure.

[0003] DE 42 40 125 A1 discloses a hydraulic lowering device for swap bodies that uses pivoting support elements to raise and lower the body. A pivoting foot element is arranged on the floor of each support element.

[0004] It is therefore an object of the present invention to provide a support foot for swap bodies which enables support using simple means and is effective in handling.

[0005] This object is achieved with a support foot having the features of claim 1.

[0006] In the support foot according to the invention, a pressure distribution plate is mounted on the lower support tube so that it can move freely about a pivot axis, the pivot axis being arranged centrally in a lower region of the support tube and an upwardly projecting wall on the pressure distribution plate being penetrated on opposite sides of the support tube. The lower support tube and the pressure distribution plate therefore form a unit which can be pivoted together from the support position to a raised position. The user therefore no longer has to worry about the positioning of the pressure distribution plate, since due to the weight force it is always arranged at the bottom in the support position and can be placed on the ground. Securing the pressure distribution plate is not necessary, since it is aligned by the weight loads and the lower support surface.The axis of rotation passes through both the support tube and the walls arranged on opposite sides of the support tube.

[0007] According to the invention, the two walls are formed integrally with the pressure distribution plate. The pressure distribution plate can be made of a bent steel sheet, thus enabling stable fixation of the pressure distribution plate and reducing the number of components. The pressure distribution plate can protrude on opposite sides of the lower support tube in the support position to reduce the distributed load on the ground. For example, the area of ​​the pressure distribution plate can be at least three times as large as the cross-sectional area of ​​the lower support tube. The pressure distribution plate can, for example, be between 400 cm 2 and 500 cm 2 be big.

[0008] In one embodiment according to the invention, the lower support tube has a curved lower end face. This achieves a particularly compact design because the lower support tube and the pressure distribution plate can be mounted at a short distance. By pivoting the flat pressure distribution plate, the distance between one end face of the tube and the pressure distribution plate is preferably kept constant, with the end face of the lower support tube then being arranged at a predetermined radius around the axis of rotation. This also reduces the risk of injury when pivoting the pressure distribution plate.

[0009] The axis of rotation is preferably arranged immovably in the axial direction via a securing element, so that the pressure distribution plate is held captively on the lower support tube.

[0010] The support tube can preferably be aligned horizontally with its longitudinal direction in a raised position of the support foot. In this case, the pressure distribution plate is preferably arranged on an upper side of the support tube in the raised position, so that the storage space for the support foot is reduced. The support tube and / or the pressure distribution plate can be fixed in the raised position by a latch, which is preferably arranged on the section of the pressure distribution plate protruding from the support tube. The pressure distribution plate is then pivoted by 90° relative to the support tube when pivoting into the support position, and the support tube is likewise pivoted by approximately 90°.

[0011] The invention will be explained in more detail below using an exemplary embodiment with reference to the accompanying drawings. They show: Fig. 1 a perspective view of a support foot according to the invention; Fig. 2 a detailed view of the pressure distribution plate on the lower support tube in a support position, and Fig. 3 a detailed view of the lower support tube with the pressure distribution plate in a raised position.

[0012] A support leg 1 for swap bodies of trucks comprises a horizontal leg 2 pivotally mounted on a tube 3. The horizontal leg 2 is connected to a leg 4, which is arranged vertically in the support position and comprises an upper tube 5 and a telescopic lower support tube 6. The vertical leg 4 can be pivoted from the support position into a raised position in which it is oriented substantially horizontally.

[0013] A support strut 7 is mounted on the vertical leg 4, rotatable about an axis 9, and can be secured to a frame of the swap body via a retaining element 8. The support strut 7 can be secured to the vertical leg via a locking mechanism. A base element 10 is mounted on a lower section of the lower support tube 6. The base element 10 comprises a pressure distribution plate 11 and two upwardly projecting walls 12. The pressure distribution plate 11 and the walls 12 can be formed integrally with one another, for example, from a bent metal sheet.

[0014] The base element 10 is rotatably mounted on the lower support tube 6 via a rotation axis 13, wherein the rotation axis 13 is held immovably on the support tube 6 in both the axial and radial directions. The rotation axis 13 is formed by a bolt that passes through the support tube 6 in a central region and is held on the walls 12.

[0015] In Fig. Figure 2 shows the base element 10 with the lower support tube 6 in detail. The rotational axis 13 extends through the two upwardly projecting walls 12 of the base 10 and is secured in the axial direction by a locking element 14, which prevents the rotational axis 13 from shifting in the axial direction. The pressure distribution plate 11 is at least three times the cross-sectional area of ​​the lower support tube 6 and, in the support position, protrudes from the lower support tube 6 on opposite sides to provide stable support.

[0016] In Fig. 3 shows the lower support tube 6 with the base element 10 in a raised position. It can be seen that the lower support tube 6 has been pivoted approximately 90° and the lower end face 15 of the support tube 6 is curved. The end face 15 is arranged at a constant distance from the rotation axis 13, so that when the pressure distribution plate 11 is pivoted, the distance between the pressure distribution plate 11 and the end face 15 remains approximately the same.

[0017] The lower support tube 6 is designed as a hollow profile, and the two curved end faces 15 are connected to each other via a profile wall 16, which is flush with the end faces 15 and cut at an angle. As a result, the distance between the pressure distribution plate 11 and the end face 15 remains unchanged when pivoting.

[0018] In the raised position, the pressure distribution plate 11 is located on top of the lower support tube 6, and a latch 17 is arranged on the protruding portion of the pressure distribution plate 11, which holds the support leg 1 in the raised position. The latch 17 can be moved or pivoted according to the arrows to secure the support leg 1 in the raised position and to unlock it when necessary. When the latch 17 is removed from the pressure distribution plate, the support leg 1 can pivot downwards, and the pressure distribution plate 11 automatically returns to the lower position due to the weight forces, which Fig. 2 is shown.
